Out of 203 Atule mate fish specimens examined, only 23 had parasitic monogeneans, Monaxinoides austrosinensis from the Gulf of Thailand. The prevalence and intensity of infection were 12.81% and 1.27%, respectively. Morphologically, the leaf-like body of M. austrosinensis was 5.88–8.07 mm long and 1.84–3.34 mm wide with a fan–shaped opisthohaptor at the posterior end. Numerous pores on the body tegument were observed using scanning electron microscopy. The muscular structure around the vaginal pore presented a number of sensory papillae. The opisthohaptor was one row of clamps which appeared similar in size. The presence of M. austrosinensis in this study is a new locality record in Thailand and is the first description based on scanning electron microscopy
